One idea could be that the OC is a powerful bender who saves a group of characters of different genders from a great danger. In return, they all develop feelings for the OC and form a harem. For example, if the OC is a water bender, they might save some earth benders and fire benders from a group of bandits. Another idea is that the OC has a special ability that is needed to save the Avatar world, and as they travel around recruiting help, different characters join them and fall in love.
To develop the characters, start with their appearance. Describe how they look, their clothing style, etc. Then, consider their goals and dreams. A character might want to become a great Avatar or just find a peaceful place to live. Their relationship with the OC should also be developed. Is it love at first sight or does it grow slowly over time? Also, their relationships with each other in the harem can add depth. Do they get jealous or do they support each other?
First, consider different elemental backgrounds. For example, a Fire Nation girl who is an outcast because she doesn't believe in the aggressive ways of her nation. She could have a soft side and be interested in art or healing instead of fighting. Another way is to play with different personalities. A shy Earth Kingdom boy who is really strong in earthbending but lacks confidence in social situations. You can also mix in different species. Maybe a winged lemur - like humanoid who has a carefree and mischievous personality.
One idea could be the OC having to navigate through different elemental cultures within the Avatar world to gain the trust and love of the harem members. For example, if part of the harem is from the Water Tribe, the OC might have to learn their traditions and help with community issues like water shortages. Another plot could involve the OC having a unique bending ability that draws the attention of the harem. Maybe they can bend a new element or have a special way of using an existing one. This would make them both a target and a hero in the Avatar universe.
When creating an Avatar OC for an airbender fanfiction, it's important to blend them into the existing Avatar world. Their name should have a certain feel to it, like it could belong in the Avatar universe. You can draw inspiration from real - world cultures that influenced the Avatar world. Their goals and dreams are another aspect to focus on. Are they trying to master airbending? Or are they on a quest to find other airbenders? Their motivation will drive the story, and by carefully crafting these aspects, you can create a memorable Avatar OC for your fanfiction.
In Avatar: The Last Airbender fanfiction, a blind OC could have a really interesting backstory. Maybe they were born blind in a tribe where physical ability in bending was highly prized. This could lead to them being an outcast at first. But as the story progresses, their unique perspective and abilities could prove invaluable. They might be able to sense an approaching enemy before anyone else, or have a special connection to the spirit world that is enhanced by their lack of sight.
There could be a wise old sage who has foreseen the OC's rebirth as the dark avatar and decides to guide them. This sage might have knowledge of ancient prophecies that suggest the OC can use their new power for good. Also, an unexpected ally could be an enemy of a greater evil. They realize that the OC's power as the dark avatar can be used to fight against a common foe.
Imagine an OC named Eira. She's a half - Fire Nation, half - Water Tribe firebender. This makes her an outcast in both societies. Her firebending is a blend of the passion of the Fire Nation and the fluidity of the Water Tribe. She has long, black hair and blue - tinted eyes. Eira has a pet dragonfly - bunny that she found as an abandoned baby. In her fanfiction journey, she tries to find a place where she belongs while using her unique bending abilities to help those in need. She can bend fire in a way that looks like water flowing, which is both beautiful and powerful.
One common theme is the development of relationships between the main character and multiple characters in the Avatar universe. For example, in an Avatar: The Last Airbender harem fanfiction, the main character might be Aang and the story could explore his different relationships with Katara, Toph, and other female characters. Another theme could be the power dynamics within the harem, like how each character contributes to the group or challenges the main character's leadership.
One common theme is the power struggle. In these fanfictions, characters from both Naruto and Avatar universes often have to deal with their own powers as well as compete for the affection in the harem. For instance, a Naruto character with strong ninjutsu may have to prove himself against an Avatar character with bending abilities.
